How to create one long string from a collection of values

[comn8u]

How would I create one long string from a collection of values? What I mean by this is - say that you have a listbox of e-mail addresses and you want to be able to put them all together with semi-colons after them and into one string that will be used as an e-mail address.

(e.g.)
LIST BOX:
user@domain.com
user1@domain.com
user2@domain.com
user3@domain.com



String:
user@domain.com; user1@domain.com; user2@domain.com; user3@domain.com





Thank you all for your comments, its really helped me out tremendously!

If you have filled your DropDownList using a DataSet it will be easier, what you have to do is this:

Dim X as Integer
Dim YourLongString as String

For X = 0 to Data_Set_Emails.Rows.Count()
YourLongString = DataSet_Emails.Tables("Emails").Rows(x)("email")
Next

If you have a listbox called lstEmail:

Dim s As String = ""
Dim i As Int16
For i = 0 To lstEmail.Items.Count - 1
s &= lstEmail.Items(i).ToString() & "; "
Next
's = the string
MessageBox.Show(s)
